Update to update, 8 min delicate wash, low heat, just small amount of detergent, Downey if you like it like me. Take them out, place in drier, about 20 min, low heat, just a tad wet, but clean as hell.....then place them back in car, I call it freeze dry since about 10 degrees out here. Velcro...all good, foam on the back....all good. This myth is BUSTED!!!!! LOL..Thanks for the easy tip though, never thought of that until tonight. Better than taking the suckers out and washing them, then scrubbing them, and letting them sit in the sun. Also, since my sprinklers and hose are turned off so the pipes don't crack....easy, no work at all. Except popping open the beer.....:rofl:
Now, if you throw them in on heavy wash, high heat, throw in 2X soap, and place on large load.....then throw them in a drier on high heat, for an hour...guess you will mess them up. Actually, the velcro works better now.
Again, this is just my personal test...others, if you fear a washer...do not attempt the following stunt. :yikes: LOL
